Для сибирских поездов нужен не душ, а крылья, т.е. бюджетная авиалиния до центральных городов. Проводить отпуск (или оплаченное рабочее время) в тесном кубрике с тремя храпящими попутчиками — это растрата жизни/денег. Кому хочется покататься (а это есть, и тут тоже), поезд совсем другой будет, и там не только душ, но и ресторан должен быть
нормальный, с нормальной едой и обстановкой. И второй этаж там тоже пригодится, чтобы не в коробочке сидеть, а прогуляться и поглазеть на окресности. В общем, надо думать, а не просто прыгать.
Вот пример поездов для аналогичных просторов:

The Ghan is a passenger train between Adelaide, Alice Springs, and Darwin on the Adelaide–Darwin railway in Australia. Operated by Great Southern Rail, it takes 54 hours to travel the 2,979 kilometres (1,851 mi) with a four-hour stopover in Alice Springs.
The service's name is an abbreviated version of its previous nickname The Afghan Express. This nickname is reputed to have been bestowed in 1923 by one of its crews. The train's name honours Afghan camel drivers who arrived in Australia in the late 19th century to help find a way to reach the country's unexplored interior.
A contrary view is that the name was a veiled insult.

The Indian Pacific is an Australian passenger rail service that operates between Sydney, on the Pacific Ocean, and Perth, on the Indian Ocean. It is one of the few truly transcontinental trains in the world. The train first ran in February 1970 after the completion of gauge conversion projects in South and Western Australia.
The train's route includes the world's longest straight stretch of railway track, a 478-kilometre (297 mi) stretch of the Trans-Australian Railway over the Nullarbor Plain.
The service was originally operated jointly by the New South Wales Government Railways, South Australian Railways, Commonwealth Railways and Western Australian Government Railways, until February 1993 when Australian National took full ownership.
